Security Bulletins for Xerox Products (11)

The Xerox devices ColorQube® 9201/9202/9203, ColorQube® 9301/9302/9303, WorkCentre® 232/238/245/255/265/275, WorkCentre® 5030/5050, WorkCentre® 5135/5150, WorkCentre® 5632/5638/5645/5655/5665/5675/5687, WorkCentre® 5735/5740/5745/5755/5765/5775/5790, WorkCentre® 6400, WorkCentre® 7525/7530/7535/7545/7556, WorkCentre® 7655/7665/7675, WorkCentre® 7755/7765/7775, WorkCentre® Bookmark 40/55, WorkCentre Pro® 232/238/245/255/265/275 were shipped with certain protocols enabled that, if properly exploited, could be used to gain
unauthorized access to the system. These particular protocols should not have been present in the production configuration and need to be removed from that configuration to minimize the possibility of unauthorized system access.

A software solution (patch P49) is provided for the products listed. This solution will remove from the production configuration the unwanted protocols in question so they can’t be exploited to gain unauthorized access to the system.

This solution is designed to be installed by the customer. The software solution is compressed into a 3 KB zip file and can be accessed via the link below or via the link following this bulletin announcement on the Xerox Security Site.

NOTE: We are re-issuing this bulletin due to a spelling error of the name of one of the researchers. No technical content in the bulletin has changed.

Vulnerabilities exist that, if exploited, could allow remote attackers to insert arbitrary code into the device. This could occur with a specifically crafted Postscript or firmware job submitted to the device. If successful, an attacker could make unauthorized changes to the system configuration; however, customer and user passwords are not exposed.

As part of Xerox’s on-going efforts to protect customers, the ability to accept these specially crafted jobs can be disabled for the affected products listed in the bulletin. Links for the software needed are contained inside the bulletin.

Vulnerability in the WorkCentre M35/M45/M55, WorkCentre Pro Color 32/40, and WorkCentre Pro 35/45/55 ESS/ Network Controller could cause Immediate Image Overwrite to fail in a specific instance with no indication after an unexpected power loss.
